STRAW-BALER ATTACHMENT FOR THRESHING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 721,105, dated February 17, 1903. Application and lingua 18,1902. `serial No.'1zo,115. (Nomaden To all whom t may concern.-

Beit knownthat I, ANDREW J. SPENCER, a citizen of the United States, residing at Indianapolig in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Straw-Baler Attachments for Thresliing-Machines, of which the following is a specification.

This invention relates to improvements in baling-presses, and is specially intended for use with a threshing-machine to bale the straw as it comes from the machine; but it can be used with advantage for all baling purposes.

The object of the invention is to provide a strong, durable, quick-acting, and easily-operated portable baling-press, to provide a press in which the baling process will be practically continuous, and in which a smoother and more symmetrical bale will be produced with less than theusual amount of power.

Other objects and advantages contemplated by the invention will be fully described, and pointed out in the'claims. y

I accomplishthe objects of the invention by the inechanism illustrated in the accompanying drawings, in which- Figure 1 is a topor plan view of my invention; and Fig. 2, Aa side elevation of same, showing also the discharge end of` a separator and connection of separator with the press.

Like characters of reference indicate likev parts throughout both views of the drawings. 3 3 are th sides, et the top, and 5 the bottom, of my press-body. The sides have central longitudinal openings 6, through which access is aorded to the bales when it is desired to tie them on four sides, as is desirable whenv short chalfy material is being baled. The top 4 of the press has the opening 7, through which the straw is introduced, and it is also provided with the longitudinal slots 8 8. The bottom 5 is solid, with the exception that it has slots (not shown) like 8 8 of the top, which with saidslots 8 8 provide means whereby the 'wiresor twine for tying the bale Vare easily placed in position on the bale in the pressand tied. Over the top 4 and under the bottom 5 are the cross-bars 9 9, the projecting ends of which are joined by the rods 10 10, on the threaded ends of which are nuts 11 11, and by screwing the nuts in Ybale sides, aswould otherwise result.

reason that the newly-forming bale is pressed against the finished bale ahead of it, pushing the latter out of the. press as the new one is completed, and the sizeof the outlet with relation to the bale determines the force required to eject the balefrom the press, and

consequently the amount of compression given to the new bale by the plunger. The outlet from the pressis further restricted by drawing in the sides 3 3, as shown'by comparison withthe parallel dotted lines inFig. `1.

Secured'to'the Vsides 3 are the standards 12 12, which give support to the cog-wheels 13 13. Iltis a plunger which is mounted in the press. It has the side plates 15-15, which work in the opening 6 of the-press sides 3 to hold the plunger in vertical position and also to restrain the straw and keep it from projecting through the opening 6 to form ragged The sides-Sthroughoutthe length of the plungerstroke are held parallel by standards 12 and 12a." The plunger alsohas the horizontal inwardly in the process of compressing thel bale. The plunger ltis connected with wristpins 16 on the'wheels 13 by the pitmen 17.

The pitmen are in practice the ends of a U- shaped bar, the ends of the U having eyelets which receive the wrist-pins and the crosslbar of the U resting against the plunger outside thereof and being secured thereto by staples 18. Y

' The upwardly-projecting ends of the'standards are perforated to form bearings for the shaft 19. 'The shaft 19 has p inions 2O 20, meshing with the cog-wheels 13 13. One lend of the shaft 19 hasA the pulley 2l, which is 95 connected by belt 22 with any'suitable motor, and the opposite end of the shaft has the iiywheel 23.

The still higher ends of standards 12 are perforated to receive the bar 24. The ends of the bar are bent down to form arms 25, which terminate in the paths of lugs 26, pro- ICO jecting in from the inner sides of wheels 13 13. The bar between the standards is bent forward close to each standard and at right angles to the arms to form the arms 26 26, and these are bent so their cross-bar 27 will fall between the sides 3 of the press through the openingr 7, and said arms 26n are again bent at right angles to form the parts 28, approximately parallel with the arms 25. To the arms 28 the plate 29, having serrations or fingers along its lower edge, is adjustably secured by bolts 30, having hooks to engage said arms.

By contact of arms 25 with the lugs 26 the finger-bar will be depressed, thereby forcing the straw down through opening 7 into the path of the plunger. The arms are raised by any suitably-arranged springs, such as those shown at 31 of the drawings. It will be noted that I prefer to use three lugs in close relation to each other in order to give three strokes close together with a, longer interval between the three.

The bales will be separated from each other by means of the movable partitions 32, which are dropped through opening 7 in front of the plunger, the arms supporting the finger-bar 29 being separated, as shown, to afford convenient access to said opening by an operator walking on top of the press. The partitions have vertical grooves 33, through which the ties are introduced.

34 represents the end of the thresher. My press is mounted on wheels 35 and has the tongue 36, which is coupled to the rear axle of the thresher. The end of the thresher is connected by canvas walls 37 with the mouth of the press, as shown in Fig. 2.

Having thus fully described my invention, what I- claim as new, and wish to secure by Letters Patent, is-

1. In a baling-press, a press-body having slotted top, bottom and sides, screw-bolts at the discharge end of said body to adjust the width of the side slots to change the size of the discharge end of the press, a plunger having side plates that Work in said side slots at the receiving end of the body and having a table or platform and standards to maintain a uniform width of said side slots for the length of the plunger-stroke.

2. In a baling-press, a press-body having slotted top, bottom and sides, screw-bolts at the discharge end of said body to adjust the width of the side slots to change the size of the discharge end of the press, a plunger having side plates that work in the said side'slots at the receiving end of said body, standards to maintain a uniform Width of side slots for the length of the plunger-stroke, cog-wheels, pitmen connecting said cog-wheels with the plunger, a shaft above the cog-wheels having pinions meshing therewith and having a iiywheel and a pulley.

3. In a baling-press, a press-body, a plunger, a pair of crank-wheels connected by pitmen with said plunger said wheels having pins or lugs projecting inwardly from the rims of the wheels, a pusher-frame pivotally secured above the crank-wheels and having arms projecting into the paths of the said lugs whereby the pusher-frame is lowered into the mouth of the press and a serrated plate adjustably secured to the free end of the frame.

4. A press-body having slotted sides and longitudinally-slotted upper and lower walls, a plunger in the body having sidewings working in the side slot-s of the body, cog-wheels, pitmen connecting said cog-wheels with the plunger said cog-wheels having lugs projecting inwardly from their rims, a shaft mounted above the cog-wheels having pinions meshing therewith and also having a driving-pulley and a liy-wheel and a pusher-frame pivotally secured above the shaft, said frame having arms which enter the paths of the lugs on the cog-wheels whereby the frame is lowered by contact of the arms with said lugs, a spring or springs to raise the frame and a finger-bar secured to the free end of the frame.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 5th day of August, A. D. 1902.
